Question

当我为ng-app属性添加名称时，我无法弄清楚为什么Angular会抛出错误。

Chrome中的错误是“未捕获的对象”，位于angular.js的第36行function minErr(module) {

我正在使用缩小的角度库from googleapis。

如果我只是<html ng-app>，则没有错误。只要我<html ng-app="app">，Angular就不再有效了。

编辑：添加我的代码。

Answer 1

您需要创建appModule才能使用命名应用。

<html ng-app="App">
  <head>
  <script>
    var app = angular.module('App',[]);
    app.controller("PlansCtrl", function($scope) {
     $scope.plan = {"id":1,"nam ....
    });
   </script>
   </head>
   <body ng-controller="PlansCtrl"></body>
</html>

Answer 2

我建议在第78行的angular.js文件中添加一个断点

return new Error(message);

并查看消息以查看错误。

你也可以在Chrome控制台上使用F12来查看是否有错误。

另外请确保在app.js中更改应用名称

第二行：

 angular.module('App',

Angular.js＆＃34;没有对象＆＃34;添加ng-app名称时出错
